To' all whom it may concern Be a known that'I, wanna J. BELLS, a

citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented certain new. and useful Improvements in Bottle-Filling Machines, of which the following is a specification- This invention relates to bottle filling machines, and particularly to automatic cutoffs therefor. a

The primary object of the invention is to provide means for use in connection with the filling nozzle of a bottle filling machine which operates automatically upon the liquid level in the bottles attaining a predetermined height to cut ofi the flow of liquid from the nozzle. v

A further object of the invention is to provide a device of this character which iscapable of being readily adjusted whereby the same may be applicable to bottles or jars varying in heights or shapes. i

A still further and particular ob-jectof the invention is to provide a device of the above mentioned character which is of simple construction, which is composed of but few readily assembled parts, all so constructed. and arranged as: to prevent wear, breakage or derangement of the same, Which is positive in operation. and which will prove thoroughly efficient in the attainment 'of the ends. for which it is designed. a 1

WVith. these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel formation, combination and arrangement of parts, all as will be describedfimore fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims. Z

The invention will be best understood with reference to the accompanying drawings, wherein': 1 I

Figurel is a fragmentary side elevation of a bottle filling machine, andillustrating the practical application of a cut-off device constructed and arranged in accordance with the invention;

Fig. 2 is a sectional view takenvertically throuih the mechanism, and illustrating the cut-off mechanism in open position;

' ,Fig. 3 is a transverse sectional view taken substantially upon line 33 of Fig. 2;

, Fig. 4 is a similar view on line 44 of Fig.1.

The invention resides generally. in the probottle beneath the nozzle. lifted, a valve within thenozzle is opened,

vision of a sliding frame adjacent the cut- 1 andlifted during the insertion of an empty As the frame is whereupon liquid within the tank or reservoir fiows from the same andinto the bottle.

Associated-with the frame is a latch which" normally maintains the frame and valve carriedtherebyin open position, and an electromagnet 1s provlded near the catch for withdrawing the same when the liquid'level within the bottle has reached a predetered when moved in one direction to close a circuit to withdraw the latch and to permit the valve to move to closing position.

liquid tank or reservoir is indicated at '5,

and i's pro'vided'with a reduced filling outlet or nozzle 6. This nozzle extends down- Wardly through a base or block 7 the latter being either secured to the "tank or upon suitable supportsadjacent thefilling table. The walls of the tank bottom at the juncture of the nozzle therewith form seat,--as indicated-at 8.

' TArranged for sliding movement toward and away from'the discharge nozzle is a frame 9." This frame is of substantially inverted U-shapeand has it's legs projecting upwardly through suitable housings 10 on opposite sides of the discharge-nozzle. The

'bight portionv of thefU-frame comprises a' loop-indicated at-11,- and which is adapted spring 13 located withinthe housing-encircling the leg of the frame, and beinglar- 1 ranged in such manner as to normally force the frame downwardly.

The stem-14 projects belowthe vdischarge end of the nozzle and is bent or twistedlaterally as shown'at 16, and is connected to one of the legs of the .U-frame 9. J

Arranged adjacent one of the legs of the frame 9 is a latch or catch member 17, the latter being held normally in, the path trav-. ersed by the stop member 12 upon the adjacent leg by an expansion spring 18. The

outer face of the latch is beveled inwardly and downwardly as shown so that the stop 12 may pass upwardly within the hous ng 10 but will be arrested in its downward travel by engagement with the outer upper extremity or shoulder of the, latch member, as will be readily understood.

From this construction, it is apparent that the frame 9 and the valve associated therewith are. capable of sliding upwardly to. open position, and are held against downward movement by the. catch member-17. Upon retraction of the latch, the stop 12 on the. frame leg Will be released, and" the spring 13 will operate to force the frame andvalve downwardly into closed position. Associated with the latch 17" for withdrawing the same from engagement. with the stop 12 at certain times, is an electromagnet 19. lhis electromagnet is mounted upon the the discharge nozzle 6, and projects below the lowermost end of the same. The. discharge nozzle is provided with a longitudinally extending groove portion 25, which houses the rod 24, and a stop or limiting member 26 is arranged upon the nozzle to limit thelower movement of the rod; This rod is provided adjacent its upper end with an angularly extending portion which can ries a contact plate 27, the latter being insulated from the IOCl, and: being ofa length sufiicient to bridge the contacts 23 when movedinto engagement with the same. The

outer extremity of the angular portion of the rod 24 is bent upwardly as at 28 and slides within similarly disposed grooves or openings 29. The lower extremity of the rod carries a float, such as a cork 30, and the latter is preferably arranged upon the rod in such manner as to be adjustable vertically upon the same.

The nozzle 6 is of such diameter as will permit of the mouth and neck portion of the bottle inclosing the same. The float 30' is also adapted to extend within the bottle opening, and must, therefore, of necessity be of narrow diameter. In filling a bottle,

The legs of the. frame 9: are. preferably provided with spaced adjustable stop meinbers 3:1 and 32 respectively, the former limiting the downward, movement of the. frame,

while the latter limits the upward movement of the same. As illustrated in the drawings, these stops may be in the form of nuts threadedly engaged: upon the legs 9 of the U-frame. By adjusting. these nuts, it is apparent that theextent of movement of the frame may be readily regulated.

Will-lathe above is a description, of the preferred embodiment of' the invention, it is. apparent that. various changes in the minor details of construction and arrangement of parts may be resorted to, if desired, without departing from the spirit of the invention or exceeding the scope of the claims.

2; In a bottle filling'mac'hine, the combination with the filling nozzle, of a valve in said nozzle, a sliding'frame, a connection 1,242,313 Y r 7 H between said sliding frame and said valve, means tending normally to hold said frame in valve closing position, a catch for looking said frame with said valve open, an electromagnet associated with said catch and adapted when energized to move the same to frame releasing position, a float, and a bridge member controlled by the movements of said float for closin said electromagnet, su scribed.
